Let A = \{3, 5, 7\}; B =\ x|x is an even whole number less than 11), C = \{2, 8, 10, 12\} and D =\ x|x is an odd whole number less than 12). Find A cap B.

Question

Select the correct choice and fill in any answer boxes in your choice below.

OA. A cap B=\ Box\ (Use a comma to separate answers as needed.)
OB. The solution is the empty set.

Answer 1

The intersection of sets A and B means finding the elements that are common to both sets.

A = {3, 5, 7}
B = {2, 4, 6, 8, 10}

The only number that is present in both sets A and B is 6.

Therefore, A cap B = {6}

So, the correct choice is:

OA. A cap B = {6}
